Intelligent double-stage double-precision load cell

Abstract

The invention discloses an intelligent double-stage double-precision weighing sensor, which includes a mounting seat, a first precision weighing sensor, a second precision weighing sensor, a supporting foot and an elastic supporting member; the mounting seat is provided with a mounting plate portion And the force-guiding support part used to transmit the pressure received by itself to the mounting plate part; the elastic support part, the first precision load cell, the mounting plate part, the second precision load cell, and the supporting feet are sequentially crimped and arranged; the elastic support The top end of the part is higher than the top end of the force guiding support part in a free state, and the top end of the elastic support part moves down when it is under pressure. The invention has two-stage continuous measuring ranges, and has different accuracy values ​​in each ordering range.

Description

technical field [0001] The invention belongs to the technical field of weighing sensor structure design, and in particular relates to an intelligent double-stage double-precision weighing sensor. Background technique [0002] The weight electronic scales currently on the market are mainly composed of a loading board, a display screen, an adjustment button, a power module and a load cell for supporting the loading board. When the weight of the loaded object exceeds the preset value, the display screen will start to display the value. The preset value is generally 5 kg; in addition, the maximum range of this kind of weight electronic scale is generally 180 kg, and the accuracy value is only 100 grams. The error is large. Therefore, this traditional weight electronic scale can not be used for other purposes except weighing the body on weekdays, especially it cannot be used as a kitchen electronic scale. And existing kitchen electronic scale, its precision value can reach 1 gra...

[0002] The weight electronic scales currently on the market are mainly composed of a loading board, a display screen, an adjustment button, a power module and a load cell for supporting the loading board. When the weight of the loaded object exceeds the preset value, the display screen will start to display the value. The preset value is generally 5 kg; in addition, the maximum range of this kind of weight electronic scale is generally 180 kg, and the accuracy value is only 100 grams. The error is large. Therefore, this traditional weight electronic scale can basically not be used for other purposes except for weighing, especially it cannot be used as a kitchen electronic scale.

However, the existing kitchen electronic scales have an accuracy of 1 gram or even less, but their range generally does not exceed 10 kilograms, so they cannot be used as weighing scales.
